Summary

Every recorded hook call normalizes its module id through getPublicModuleId, so the same id is recomputed once per plugin per hook. For dependency ids this includes a path.relative call, which made it the most expensive part of the inspect hot path in projects with many node_modules modules. This PR caches the result per environment context.

Changes

• getPublicModuleId stores its result in a per-env Map<id, publicId> and returns the cached value on later calls.
• The cache is cleared when the env's root changes, because the result depends on it.
• The cache is capped at 10,000 entries and cleared when full. Ids can carry HMR timestamps, so without a cap it would keep growing over a long dev session. After a clear, ids are simply recomputed.

Impact

Measured locally with a synthetic project (5,000 modules × 200 lines, half of them under node_modules, 20 plugins), median of 10 runs:

	Before	After
Transform time	964 ms (+39% vs no inspect)	822 ms (+19% vs no inspect)
recordTransform (CPU profile)	167 ms	21 ms
normalizeModuleId (CPU profile)	154 ms	9 ms

This roughly halves inspect's overhead on transforms when a project has many dependency modules. With no node_modules modules the saving is small (~20 ms), since only the string replacements are skipped.
